Always been my experience as well. And it isn't just IE; lots of programs cache those kinds of results.

As in, Internet Explorer doesn't get the /FLUSHDNS right unless it's closed when the /FLUSHDNS command is run? Interesting if true...

After clearing the host record (not ptr records existed) I ran ipconfig /registerdns on his machine and his correct address appeared, along with the correct ptr record. My own machine, though retained the bogus IP address in the local DNS cache, and I could see it with ipconfig /displaydns I flushed the dns cache, and all was sweetness and light. The question: How long does dynamic DNS data remain in the cache? Especially helpful would be a link to where this is documented.
